Experimental Plan
Experimental Purpose:
Observe the impact of changes in each parameter on atomization effect.
Experimental principles:
The parameters of the atomized effect are: the average diameter of the droplet group, the size distribution of the drip group, the fog angle, the flow density density, the flow density density And range.
Due to the limitation of the experimental conditions, the average diameter and size distribution of the droplet droplet cannot be quantitatively measured, so it is initially formulated to perceive the size of the fog droplet.
We use two laser pens to measure the fog angle and range of the fog. The Dadar effect of the atomized liquid droplet group enables us to clearly see the traces of lasers through the droplet group to measure the atomized cone angle. In the same way, we can also use a laser pen to measure the range of atomization.
The flow density is the liquid volume on the cross -sectional area of the unit during the unit time. We can know the distribution of traffic density through quantitative methods. The atomized liquid can be used in ordinary water. Place a row of test tubes evenly under the liquid. After the experiment is over, the volume of the water in each measuring tube is measured, and the amount of flow density can be obtained by the volume.
Experimental Equipment:
Creative pump, cup, a measuring tube (10ml and 50ml each), air pump, two -phase flowing nozzle, background black cloth, straight ruler, laser, laser, laser, laser, laser, laser, laser, laser, laser, laser, laser, laser, laser, laser, laser, laser 3 pens, 8 test tubes, cameras and tripods, water.
Experimental model:
Experimental steps:
1. Check the experimental equipment2. Connect the peristaltic pump, rubber tube, tube, tube, Burn a cup, measure the tube. The measurement of the liquid under the speed of the measurement at a certain speed is determined to establish the relative relationship between the speed of the peristaltic pump and the liquid flow at a certain speed.
3. Connect the liquid supply and gas supply device. Open the laser pen.
4. Adjust the nozzle structure. The setting pressure is 0.15MPa and the speed is 40R/min. Adjust the nozzle structure. Select the best group of atomization effects for the next group of experiments.
5. Adjust the speed of the creep pump is 10,20,30,40 and 50 (the unit is R/min), and the pressure is 0.15MPa. A group of experiments.
6. Maintain the speed of the best atomization effect selected in the previous group of experiments, change the pressure, select 0.1, 0.15, 0.2, 0.25, 0.3 (unit MPA), observe which set of atomization of atomization The effect is the best.
The group of experiments with the best atomization effect, place a row of test tubes below. After the experiment is carried out, the volume of the water in each test tube is taken.
